The Gecko can stick upside down on any surface, in any condition. Like the Gecko’s foot, Dunlop’s new surface treatment technology provides superior levels of traction. Its smooth, tacky surface is also perforated for improved moisture absorption. Gecko-Tac technology provides up to 50% more grip and tack than previous Dunlop grip technologies, giving greater control, feel and precision.
